Here is a boiled down version of something happening in a real project.
`Mod1.cc`
```c++
module;
#include <ranges>
export module Mod1;
```
`Mod2.cc`
```c++
module;
#include <iterator>
#include <valarray>
#include <ranges>
export module Mod2;
import Mod1;
```
`build.sh`
```sh
CXX="/Users/rob/Dev/llvm-project/build/bin/clang++ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk -std=c++2b"
set -e
$CXX -fprebuilt-module-path=. -x c++-module Mod1.cc --precompile -o Mod1.pcm
$CXX -fprebuilt-module-path=. -x c++-module Mod2.cc --precompile -o Mod2.pcm
```
Errors:
```
